Migrated to Wordpress along with Gallery2, the choice for the same was not easy. As for a long time Mambo and custom home grown Photo Album was doing the job fine. In fact the template I used for the same was appreciated by friends. But as days passed and numbers of pictures are growing it was getting difficult to manage the same with custom gallery. But the idea to grab Wordpress and dropping Mambo is a personal one. I will not compare the two. The fact is they two are different and just I felt like blog software will be a better choice for a personal website compared to a CMS
Well there is lots of lots work left to organize the pictures now after this migration as there was no tool or script that I could use to automate the same :( Hope to finish this by end of September.
